Hi Massimo,
great job! Good to see some system in Il-2 camouflages.
Probably some minor errors, like
Zavod 1 was evacuated into Kuybyshev in the Urals in October-November
Kuybishev is on Volga river, more than 500km west of the Urals... Kuibishev is as far from the Urals as
London is far
from the Alps...
IMHO, conclusions based on "photographic evidence" only are tricky - following conclusion is a
major ommision:
In late 1944 ... the Soviets decided to extend to all planes the blue grey/dark grey camouflage that has been successful for fighters since August 1943.
... there is no any evidence of application of this directive on Il-2s, despite it would have involved thousand of planes. Usually, photos suggest that Il-2 continued to be painted in the 3 colors schemes of 1943.
Gray-dark gray scheme was utilized on Il-2s, there are photos to confirm this!
It would be good to show how that sketch from the 1944 directive looks on the late war Il-2 (in theory at least... same as you did for 2 versions of earlier 3-colour camouflage)
Regards,
